(Cl. 229-23) mechanical strength and capable of being produced at exceptionally low cost. More specifically, my invention has to do with the production of a cardboard box suitable for replacing the ordinary wooden cigar box now commonly used, and capable of production at a cost equal to but a fraction of the cost of production of the wooden cigar boxes referred to. v

The instant invention is in the nature of an improvement over the box disclosed in my copending application for Paper box and blank for producing the same, Serial No. 159,847, filed August 19, 1937, of which this application is a continuation in part, and is directed particularly to the construction of the upper corners of the box.

For manyyears cigars have Ibeen sold in wooden boxes of conventional type having end walls higher than the front and back walls, with a lid hinged to the back wall and, in closed position,l

fitting between the upward extensions of the end walls and seating upon the upper edges of the front and back walls, with its top surface ush withthe upper edges of the end walls. The cigar box; trade is averse to accepting cigar boxes which are not similar in appearance to the conventional type of box referred to, or which can be detected therefrom. It is, therefore, of primary importance that a paper or cardboard cigar box so closely simulate the appearance of the conventional wooden box as not to be easily distinguished from the latter. In constructing cardboard cigar boxes considerable diiculty has been encountered in imparting to the upper corners thereof a neat appearing and smooth iinish similar to and not readily detectable from the appearance of the upper corners of the conventional cigar box.' The primary object of the instant invention is to remedy that diiculty. More specically, an object is to provide a novel blank. foldable into box form, in association with a novel reinforcing insert, so relatedand constructed as to assure that the upper corners of the finished box will present a. smooth and neat appearance similar to, and lnot easily distinguishable from, the upper corners of wooden cigar boxes of conventional type referred to. Further objects and advantages will appear from the detail description. Y

I have illustrated my invention', by way of example, as embodiedin a box such as that com- This box is cubiform and comprises bottom d, ends e1 and e2, front f, back or rear member r and lid l, the latter being hingedly connected to the upper edge of rear member r. The box thus formed is produoed fromv the blanks of Figures 3 and 4.-, in a manner which will be described presently. For

' convenience and accuracy of description, the varinner wall members for the ends andthe'. front of the box. It comprises a back outer wall member than end vouter wail member i8, a front CII surface thereof, that'is, the surface which isv not exposed when the blank has been folded into box form. In practice, the blank is shipped flat and in partially folded condition, with members I1 and I8 overlying members I5 and I6 and tab 2II bent about crease 2I into position against the inner face of member -I8, this tab being appropriately secured, conveniently by means of a suitable adhesive, to the inner face of member I5.

This 'manner of securing the blank in partially folded condition, for shipment, is fully disclosed in my above identified application and need not `be illustrated nor described in greater detail'here.

Back wall member I is provided, at its lower edge, with a bottom flap 22, there being a folding crease 23 extending along the lower edge of member I 5 for vfolding ap 22 upward toward the inner face of member I5 into position perpendicular thereto. An elongated flap 24 extends from the upper edge of member I5 and is suitably formed for producing the lid of the box. This flap 24 may be considered as comprising an outer lid flap 25 connected at its back edge .to the upper edge of member I5 by a spacing element 26 defined by two spaced parallel folding creases 26a and 26h, and an inner lid flap 21 connected at its front edge to the front edge of flap 25 by a spacing element 28, the latter denedby two spaced parallel folding creases 29 and 30. Flap 21 is provided, at eachend thereof, `with a securing tab 3I connected to flap 21 by a spacing element 32 defined by spaced parallel folding creases 33 and 34.

, The end outer wall member I5 is provided, at

its'lower edge, with abottom flap 35, there being a folding crease 36 extending along the lower edge 'of member I6 to permit folding of flap 35 upward toward the inner face of member I6 into position perpendicular thereto. An inner wall flap 31 is -connected, at its upper edge, to the upper edge of member I6, by a spacing element 384 dened by two spaced parallel folding creases 39 and 40, the latter coincident' with the upper edge of member I5. I

The outer front wall member I1 is provided with a bottom flap 4I extending from its lower edge,

with axfolding crease 42 along such lower edge Y the upper edge of ap 43 and the upper edge of End member la 1s provided with a bottom nap 41 extending from its lower edge, with a. lfolding crease 48 along this edge permitting folding of flap 41 upward toward the inner face of member I8 into position perpendicular thereto. An inner wall flap 48 is connected to the upper edge of alsa-189 I1, respectively, are of the same height and the end outer wall members I5 and I8 are of equal height and of greater height than members I5 and I1. Spacing elements 39, 44 and 55 preferably are of equal width, corresponding in width to the thickness of the box body reinforcing insert, previously referred to and to be described presently.- Spacing elements 26, 28 and 32 are of equal width, equal to the thickness of the lid reinforcing insert previously referred to and hereinafter described. If the lid reinforcing insert is formed of material of the same thickness as the material of the box body reinforcing insert, spacing elements 26, 28, 32, 39, 44 and 50 may all be of the same width, as shown in Figure 3. Lid ap 25 is equal in width to the width of the outer end wall members I6 and I8, the width of which determines the exterior width of the box, and is of less length tha'n back member I5, the ends of flap 25 being spaced inwardly from the ends of member I5 a distance equal to the width of the spacing elements 438 and 50. The inner front wall flap 43 is equal in height to member I1 and is of less length than the latter member, the ends of flap 43 and the associated spacing element 44 being spaced inward from the ends'of member I1 a distance equal to the width of lspacing elements 38 and 50. The end inner wall flaps 31 and 49 are equal in height to end members I6 and I8 but are of less width than the latter members, being spaced inward from each end thereof a distance equal to the width of spacing elements 26 and 44. Bottom flap 22 is of slightly less length than member I5 and substantially equal in width to members I6 and I8, bottom flap 35 is of slightly less width than member I6 and is equal in length to slightly less than one-half of the length of flap 22, bottom flap 4I is equal in length to lmem ber I1 and is substantially equal in width to the width of members I6 and I8, and bottom flap 41 corresponds'to bottom flap 35. Thev differences inA .length and width of the flaps 22, 35 and 41 a matter of convenience in cutting the blank,

which preferably is cut accurately by die means,

and is not essential tov my invention.

The blank of Figure 3 is cut from sheet cardboard which may be of from medium to lightweight, the material used being of appreciable thickness and stiffness such that the blank, when folded into box form, is self sustaining and possesses considerable rigidity and mechanical strength. Eachof the inner end wall flaps 31 and 49 is provided, at each upper corner thereof, with an integral rectangular tab 53 corresponding lin height to the difference in height between the end members I6 and I8 and the back and front members I5 and I1, tabs 53 corresponding in width to the width of spacing elements 2 5 and 55. Each' of the outer wall end members I5 and Il is provided, at each upper corner thereof, with a rectangular tab 54 separated at its lower edge from the associated member I 5 or I1 by` a cut or slit 55. The slits 55 at the lower edges of tabs 54 located at the front of members I5 and Il constitute continuations of the folding crease 45, the slit 55 at the lower edge of tab 54 located at the rear of member I8 constitutes a continuation of folding crease 25b of member I5, and slit 55 at the lower edge of tab 54 located at the back of member I5 is in the same plane as folding crease of member I1, it being noted that this latter crease is in the same plane as folding crease 25h of member I5. Tabs 54are equal in width to the exterior width lof spacing elements 88- and 5I, andare slightly terial from which the blank is cut. It will be seen that when the inner end wall aps 31 and I9 are folded inward and downward into parallel relation to the'rnembers I6 and I8, respectively, spaced therefrom by the elements 38 and 5D, if tabs 54 be turned inward perpendicular to members I6 and i8, these latter tabs will cover the adjacent edges of tabs 53 and elements St and 50. This function of the tabs 58 will be explained more fully hereinafter with reference to the box body reinforcing insert.

The box body reinforcing insert is shown in fully extended position in Figure 4. The insert comprises a front element 66, corresponding in length and height to front outer wall member I1 .of the box blank, end elements 51 and 58 corresponding in height and Width tothe end inner wall flaps 31 and 9, respectively, of the box blank, and a back element formed in two parts 59 and Gli, part 59 being connected at one end to element 58 the other end of which is connected to one end of element 56, and part t@ being connected to one end of elementl connected at its other end to the other end of element 56. The end elements 51 and 53 are each provided, at each upper corner thereof, with a rectangular projection 8l equal `in Width and height to the respective tabs 53 of flaps 31 and i9 of the box blank. The lower edge of each projection Si is defined by a slit or cut t2, the slits or cuts being in the planeof the upper edges of front element 56 and parts 59 and 59 of the back element. The blank of Figure .4 is scored transversely from its outer face along lines 53 passing through the points of juncture between the lower edges of projections Si and end elements l and 58. The blank is thus foldable into rec-A tangular form so as to provide a reinforcing insert disposable within the box body within the front and end members, and adjacent the back member thereof, for imparting desirable rigidity and increase in mechanical strength to the body of the box.

The manner in which the body reinforcing insert is folded will be understood more clearly from Figure 5 of the drawings. In this figure front element 56 rand part 60 of the back element are shown folded along the scorings 53 into positions at right angles to end element 51.- Projections Si of the latter element, which projections correspond in width to the thickness of the material from which the insert blank is cut, extend over element 56 and part 68, at the ends thereof, the outer ends of projections 6| being flush with or in the plane of the-outer face of element 56 and part 60, respectively. It will be understood that the projections Si at the other end of the folded insert are disposed inthe same manner as shown in Figure 5. The blank of Figure 4 is thus readily foldable so as to form a rectangular collar or insert the end elements of which are of greater height than the front and the back elements thereof, having at each upper corner a projection 5l extending in the plane of the associated end element across the upper edge of the adjacent front or back element', with its outer end flush with the outer face of such front or back element. ,Forming the back element in two parts 58 and 80 is advantageous in thatit facilitates folding the insert blank into the form stated and maintaining it so folded during placing thereof within the body of the box.

The outer surface of the box blank is suitably lithographed or treated so that it closely simulates the wood from which ordinary wooden cigar boxes arecommonly made, such outer surface of the blank being suitably calendered or finished to that end. .'I'he blanks, in partially folded condition, previously referred to, are shipped to the cigar factory, or other place of use, as are the body reinforcing inserts and the lid reinforcing inserts, which latter will be described presently. At the cigar factory or other place of use the box blank, together with the associated reinforcing inserts, is folded into nal box form. This operation may be performed manually but preferably is performed by means of a suitable set-upmachine, with a view to low cost of production.

The cover reinforcing insert is in the form of a rectangular cardboard blank conveniently-of the same thickness as the cardboard from which the body reinforcing insert is cut, and corresponds in length and width to the outer lid flap 25 of the box blank. Preferably, the latter blank is cut fromvcardboard sheet in such manner that the grain of the cardboard extends lengthwise of all of the'elements of theI box blank,. and the lid and body reinforcing inserts are cut from cardboard strips in such manner that the grain of the cardboard extends transversely of the inserts, that is, perpendicular to the grain of the box blank, as disclosed in detail in lmy above identified copendlng application.

In constructing the box from the box blank and the reinforcing inserts,the box blank, previously secured in partially folded condition for shipment, as above described, is so adjusted, by machine or manually, that the front outer wall member l1 is disposedabove and parallel to back outer wall member i5, these two members being connected by the end outer wall members l5 and it disposed parallel to each other and perpendicular to members l5 and i1, with bottomlaps 22,

35AM and d1 extending from members i5, i6, l1 and it, respectively, substantially in the planes thereof so as to leave open the bottom of the partially formed box body.

The body reinforcing insert. folded into rectangular form in the manner above described, is then inserted into the box body through the bottom thereof with elements 66, 51 and 58 of the insert disposed at the inner faces of members It, i1 and i8, respectively, of the partially folded box blank, and the back element of the insert,

formed of the parts 59 and 6U, disposed at the inner face of back member i5 of the boxblank. Prior to insertion of the body reinforcing insert, the outer surfaces thereof may be -coated with a suitable adhesive, or the inner surfaces of the A outer wall members of the box body may be coat-4 ed with an adhesive, or adhesive may be applied to both. The insertion and positioning of the body reinforcing inserts may be performed by a sui t' able set-up machine, previously referred to, or

may be performed by hand.l 'Ihe body insert is and 33r and the back edge of flap 21. This operation may occur either preliminary or subsequent to insertion of the body reinforcing insert, but

y preferably is performed simultaneously therewith,

.when the box is folded by machine. It will be understood that, within the broader concept of my invention, the reinforcing body insert may be placed within the body of the box in any other suitablemanner. If desired, the body reinforcing insert and the lid reinforcing insert may be properiy positioned and secured to the box blank preliminary to partial folding thereof into box form, the blank, with the insert secured thereto, being then partially folded for shipment as previously explained.

After the inserts have been properly positioned and secured to the box blank, and the latter has been partially folded in ythe'manner above described, folding of the blank into box form is completed- The bottom flaps are folded into position to provide a bottom closure for the box, flap 22 being first folded into position perpendicular to member I5, flaps 35 and 41 being then folded upward into contact with the under face of flap 22,

after which flap 4| is folded upward into contact with the under faces of flaps 35 and 41, these bottom flaps folded in this manner being secured together by a suitable adhesive. F1ap 4| extends rearward from the lower edge of front outer wall member I1 thus covering up the edges of the other bottom flaps so that none of the latter is visible from the front of the box. Flaps 31 and 49 are then folded downward and inward against the inner faces of elements 51 and 58 of the body reinforcing inserts, and secured to such elements by a suitable adhesive, the spacing elements 38 and 50 of flaps 31 and 49, respectively, covering the upper edges of elements 51 and 58, respectively. This also disposes the tabs 53 of flaps 31 and 49 so 'that these tabs cover the inner surfaces of projections 5I of the body reinforcing insert. The front inner wall flap 43 is then turned downward and inward against the inner face of front element 56 of the body reinforcing insert, and is secured thereto by a suitable adhesive, spacing element 44 then extending between the projections 6I at the ends of the front of the box body and covering the upper edge of element'56. In this condition of the partially formed box, the

front ends of the projections 8|, at the front of the box, and the rearward ends of the projections 6| at the rear of the box, and the outer edges of tabs 63 and connecting elements 38 and 50 are exposed, the tabs 54 projecting-forward and rearward of the box from members I6 and I8 in the planes thereof. Tabs 54 are then bent inward at right angles to members I5 and I8 so as to extend across the outer ends of projections 6|' and over the edges of spacing elements 38 and 50, to which the-tabs are secured by a suitable adhesive. The tabs 54 also `extend over and conceal the outer edges of tabs 53. This will be clear from Figures '1 and 9.

When the tabs 54 have beenl bent into position and secured inthe manner stated, the upper corners of the box present a smoothand finished appearance, there being no readily visible edges exposed nor any lines of division between the material of the box readily visible. As previously explained the outer surface of the box blank is lithographed or otherwise suitably treated to closely simulate the .wood commonly used in constructing wooden cigar boxes of ordi- -nary type. Accordingly such outer surface has a grained finish which makes it diflicult to detect such slight lines of division between 4the materials of the box as maybe present at the upper ,corners thereof. That applies to both the fine cuts or slits 5 5 defining the lower edges of tabs 53 and to the inner edges of Vtabs 54. The 'conthe back struction of the upper corners of the box body will be readily understood from Figures 6 to 9,

inclusive, of the drawings, from which it will be apparent that these corners present a neat and finished appearance and that all of the elements thereof are firmly and effectively supported.

After the body of the box has been thus completed, the inner cover'fiap i`s folded into final form. In this operation tabs 3| are folded over onto the cover reinforcing insert 64 and secured thereto by a suitable adhesive, insert 64 and lid flap 21 being then folded over onto the outer lid flap 25`, towhich tabs 3| 'are-secured by a suitable adhesive, and spacing element 26 may then be secured, by a suitable adhesive. to the back edge of the lid reinforcing insert 64. This coinpletes the lid, which is integrally hinged to the upper edge of back member I5 for movement about the line of the folding crease 26h. Preferably, a strip 55 of kraft paper or other suitable material, is secured by adhesive to the under face of the lid, at the rear portion thereof, this strip also being secured to the upper edge of element of the body reinforcing insert and to the upper portion of the inner surface of such element. The lid, in its finished form, is equal in thickness to-the difference in height between the end members of the body andthe front and the back members thereof and, when in closed position, `has its upper surface flush with the upper edges of the ends of the box. The completed box'closely simulates in every detail the wooden cigar boxes of conventional type commonly used and cannot be distinguished therefromby the ordinary observer. In the drawings certain elements of the box have been exaggerated somewhatas to'thickness and spacing, with a view to clearness of illustration. In Figure 10, for example, the major portion of the outer lid flap 25 is shown as depressed between the tabs 3|, which depression, in theory, is present. In fact, the box, in practice, is folded in forms under appreciable pressure and the overlapping elements of the box, such as tabs 3| and the corresponding areas of the outer lid flap 25, being moistened by adhesive, are capable of being flowed or molded to a certain extent by the applied pressure. As a result, in the completely folded box, even when the outer surface thereof has not been llthographed or otherwise treated to simulate wood, no depression of the lid is visible to the eye. In like manner, the iiaps forming the bottom closure of the box are pressed and secured, together so that no spacing apart of the edges thereof are visible, the bottom of the box presenting a neat and finished appearance.

In describing the inner wall fiaps of the front and end members of the box blank as of the same height as such members, respectively, the height of such-members is considered as the distance betweenv the folding creases at the top and the bottom thereof and the height of the iiaps is considered as the distance between the lower edges thereof and the folding creases at the upper edges of such flaps. It will be understood, however, that it is not essential that the inner wall aps be of the same height as the associated outer wall members of the box blank. Preferably, however, the inner wall flaps are of tively to conceal the back element of the insert.

The box, in its final form, presents a neat and attractive appearance, so closely simulates the ordinary Wooden cigar box as to be diicult to distinguish therefrom and has met-with favorable acceptance by the trade.
